From f8d23d309809ae69c763520dababb7e845938272 Mon Sep 17 00:00:00 2001 From: Olav Kongas Date: Thu, 4 Aug 2005 17:02:54 +0300 Subject: [PATCH] USB: isp116x-hcd: remove clock() and reset() This patch removes support for user-provided platform-specific hardware reset and clock starting/stopping functions. Hardware reset was needed earlier as getting the software reset working was tricky due to the lack of documentation. Recently, a number of people using isp116x have said the software reset is working for them. I haven't heard of anybody using the clock starting/stopping.
